Abstract

In this paper, we have designed and implemented cluttering classification systems- unsupervised classifiers-for the processing of satellite remote sensing images. Implemented systems adopt various design patterns which include a factory pattern and a strategy pattern to support various satellite images'formats and to design compatible systems. The clustering systems consist of sequential clustering, K-Means clustering, ISODATA clustering and Fuzzy C-Means clustering classifiers. The systems are tested by using a Landsat TM satellite image for the classification input. As results, these clustering systems are well designed to extract sample data for the classification of satellite images of which there is no previous knowledge. The systems can be provided with real-time base clustering tools, compatibilities and components' reusabilities as well.

본 논문에서는 위성영상을 처리하기 위한 무감독분류 기법인 군집분류 시스템을 설계하고 구현하였다. 구현된 시스템은 새로운 위성영상 포맷과 군집분류 기법의 지원이 용이하고, 확장성 있는 시스템의 설계를 위하여 팩토리 패턴과 전략적 패턴 등 다양한 디자인 패턴을 적용하였다. 군집분류 시스템은 순차군집분류 기법, K-Means 군집분류 기법, ISODATA 기법, Fuzzy C-Means군집분류 기법을 설계, 구현하였으며 Landsat TM 위성영상을 분류기의 입력영상으로 실험하였다. 그 결과 군집분류 기법은 사전지식이 없는 위성영상의 분류를 위한 표본영역의 추출작업과 위성영상의 실시간 분류에 효과적인 사용이 가능함을 보였으며, 재사용성 및 확장성이 우수한 시스템을 개발하였다.
